ANTARIKSA – Plasma filaments glide from an open volcanic canyon on the sun’s surface on Sunday, April 3, 2022. The event unleashed a strong current of magnetic solar wind that is likely to present more auroras to Earth this weekend.
According to Space Weather, the fire canyon is at least 12,400 miles (20 thousand kilometers) deep and 10 times longer. British weather forecaster the Met Office confirmed that two filament eruptions occurred in the south-central part of the sun. Satellites in the extreme ultraviolet part of the electromagnetic spectrum and Earth telescopes equipped with infrared heat-carrying wavelength observation systems both saw the eruption.
The first filament exploded from the sun on Sunday, April 3 at 11.00 EDT or 22.00 WIB. The second filament eruption occurred on Monday, April 4 at around 15.00 EDT or 02.00 WIB the following day.

Both eruptions were accompanied by a coronal mass ejection (CME), which is an ejection of charged plasma from the sun’s upper atmosphere. When a CME hits Earth, it can wreak havoc on our planet’s magnetic field, causing a geomagnetic storm.
Strong geomagnetic storms can disrupt satellite links and damage electronics in orbit. In some cases, these storms can even disrupt the power grid on Earth’s surface. On the beautiful side, geomagnetic storms often present stunning aurora forms. Aurora is a light that dances at the poles. The possibility of the two latest eruptions will only cause these beautiful aurorae.
Auroras are present at the North and South poles because the Earth’s magnetic field is weakest above the poles. This allows magnetic particles from the CME to penetrate deeper into the Earth’s atmosphere in these regions. The interaction between the sun’s particles and those in the atmosphere is what gives rise to colorful glows.
According to the Met Office, Earth’s geomagnetic environment is likely to become calmer in the days following the eruption. Because the canyon of active fire has rotated away from its position facing Earth. Solar activity is likely to increase again over the next few years, scientists predict it will peak around 2025.
